What Our Customers Say…

I've been a CroppMetcalfe customer for 9 years and you have always provided outstanding service. I just had my semi-annual maintenance done, and I wanted to thank George for the truly outstanding service, professionalism, and excellent advice. He is definitely one of the best 5-Star Technicians I've had! Thank you CroppMetcalfe!

Seasonal Tips:

Don't forget, one of the easiest ways to extend the life of your heating and cooling system is to change the filter every month. So... don't forget!



Welcome to the CroppMetcalfe Family!

We are exceptionally pleased to announce W.B. Maske Sheet Metal Works, Inc. has merged with CroppMetcalfe! This merger offers exciting new opportunities for both our companies and our customers. Larry Maske, former President of W.B. Maske, wants all of his former customers to know that the transition experience will be simple and they will notice immediate benefits from the merger as well.

CroppMetcalfe was established in 1979 with the goal of creating "Customers for Life." This sustained commitment to exceptional customer service has resulted in numerous industry awards. This includes being a SIX time Carrier’s President’s Award winner, as well as winning the Air Conditioning Contractors of America 2011 Residential Contractor of the Year Award. Without reservation, Larry knows CroppMetcalfe’s team of professionals will provide you with the same level of commitment and customer service you have received from the W.B. Maske team.

What does this merger mean for you?

At first glance, everything is the same. You will still call your regular phone numbers, W.B. Maske’s 301-927-3412 or CroppMetcalfe’s 301-313-0700. Highly trained and certified 5-Star professionals will be dispatched to install and/or service your equipment. You will continue to have access to online scheduling and 24/7 emergency service. Your Service Agreement(s) will remain active and unchanged.

Please note, the roofing division of W.B. Maske has been purchased by another company, Wagner Roofing. Please call 301-927-9030 or visit for more information on that acquisition.

CroppMetcalfe is proud to offer you expanded benefits and services, including:
